Apple is dramatically increasing its security bounty rewards to combat sophisticated mercenary spyware, doubling its top payout to $2 million for critical zero-click vulnerabilities. The tech giant announced these changes to its Security Bounty program effective November 2025, positioning itself as offering some of the industry’s most competitive rewards for security researchers who uncover the most dangerous exploit chains.
Unprecedented Rewards for Critical Vulnerabilities
Apple’s updated bounty program now offers a maximum $2 million reward for discovering exploit chains that achieve goals similar to sophisticated mercenary spyware attacks without requiring user interaction. The company told Wired magazine that this represents one of the highest standing bounties in the cybersecurity industry. Even more significantly, Apple revealed that total payouts could reach $5 million for particularly critical discoveries, including vulnerabilities in beta software and Lockdown Mode bypasses.
The substantial increases extend across multiple vulnerability categories. Rewards for exploit chains requiring just one-click user interaction have quadrupled from $250,000 to $1 million. Attacks requiring physical proximity to devices now also qualify for up to $1 million, while physical access to locked devices earns researchers up to $500,000. Apple’s official security bounty page details that researchers demonstrating chained WebContent code execution with sandbox escape can receive up to $300,000.
Responding to Sophisticated Mercenary Spyware Threats
Apple’s announcement specifically cites mercenary spyware as the primary motivation for these enhanced rewards. The company stated that the only system-level iOS attacks observed in real-world scenarios have originated from mercenary spyware operations, which historically associate with state actors and typically target specific high-value individuals. These sophisticated attacks represent an evolving threat landscape that requires equally sophisticated defensive measures.
The enhanced bounty program complements Apple’s existing security features designed to counter these threats. Lockdown Mode, introduced in iOS 16, provides extreme protection for users facing targeted digital threats by strictly limiting functionality. Memory Integrity Enforcement, another key defense, specifically combats memory corruption vulnerabilities that mercenary spyware often exploits. According to Apple’s security documentation, these features have already demonstrated effectiveness in making mercenary attacks more difficult to execute successfully.
Building a Robust Security Research Ecosystem
Since introducing and expanding its Security Bounty program over recent years, Apple has awarded over $35 million to more than 800 security researchers worldwide. While top-dollar payouts remain rare, the company has made multiple $500,000 payments to researchers who discovered significant vulnerabilities. This substantial investment reflects Apple’s commitment to building a sustainable ecosystem for security research that benefits both the company and its users.
The enhanced rewards specifically target “highly advanced research on [Apple’s] most critical attack surfaces despite the increased difficulty.” By offering competitive compensation, Apple aims to incentivize the security research community to focus on the most challenging and impactful vulnerability discoveries. This approach aligns with industry trends where major technology companies increasingly recognize the value of external security research in strengthening their platforms against evolving threats.
Future Implications for Mobile Security
Apple’s substantial bounty increases signal a strategic shift in how technology companies approach cybersecurity in an era of sophisticated state-sponsored threats. The move acknowledges that traditional security measures alone cannot keep pace with rapidly evolving attack methodologies. By creating financial incentives that match the complexity of modern exploit development, Apple hopes to stay ahead of threat actors who continuously refine their techniques.
The program’s focus on exploit chains—multiple vulnerabilities used in sequence to achieve compromise—reflects the reality of contemporary cyber attacks. As CISA’s emerging threat advisories consistently demonstrate, sophisticated attackers rarely rely on single vulnerabilities. Instead, they combine multiple weaknesses to bypass security controls, making chained exploit research particularly valuable for defensive purposes.
